IMPROVEMENT IN IRON-PLANING MACHINES.

Specification forming part of Letters Patent No. 124,676, dated March19, 1872.

y To all whom it may concer-n:

Be it known that I, ALEXANDRE GAsrEL, of

' the city and county of Philadelphia and State one side of its center.Fig. 2, Plate 2, is a section taken vertically and transversely through'the machine in the plane indicated by dotted line w a', Fig. l.

Similar letters of reference indicate corresponding parts in the twofigures.

The object of this improvement is to hold the traveling bed-plate of aplaner down firmly on its ways and prevent trembling by means of a yokedbrace, which is applied to a fixed bar of an anti-friction wheel thatworks on top of a Ilan ged rack on the bottom of the said 'bedplate, andwhich is also applied to the shaft of the wheel which engages with saidrack, thereby forming, in connection with one side of the frame of themachine, a quadrangular brace,

as will be hereinafterdescribed.

The following description of my invention will enable others skilled inthe art to understand it.

In the accompanying. drawing, A A represent the horizontal and parallelways of the bed-frame, which are grooved and receive tenons formed onthe bottom of the bed-plate or table B, as shown in Fig. 2.' To thesides of the bed-frame'. is bolted the upright frame for carrying theslides. D is the vertical slide; E the horizontal slide, moved byascrew, S.

E is a carrier, which has a slight circularmotion, and b is a pivotedcutter-block, carrying a cutting-tool, a. rlhe parts above described maybe constructed in the usual well-known manner. On the bottom of thetraveling-bed B a rack-plate, c, is formed, which extends the entirelength of this bed, and which is flanged at e and toothed so as to forma rack for receiving the teeth of a spu`r-wheel, N, on a horizontaltransverse shaft, H. This wheelN receives motion from adriving-shaft, o, acting through the medium of a pinion, n, a largespurwheel f is applied loosely on a fixed horizontal admit of theapplication to the under side of this shaft H, into a groove, p, formedtherein,

of a block, t', which is set up closely to the shaft by means of abridge-plate and nuts j, thus drawing down the roller or wheel f uponthe top of the rack e. The brace h, as well as the bracket g1, areadjustable to regulate the holdl ing-down pressure of the roller f inthe first in-l stance, andto compensate for the wearing away of theroller and upper surface of the rack.v

It will be seen from the above description of my invention that I holdthe bed-plate B down upon its ways, rst, by the bar g and roller f; andsecond, by the brace h and `shaft H. I thus make the brace `serve atwo-fold purpose -to wit: It assists in holding down the bar g, and italso braces the shaft H of wheel N against vibration.

Having described myinvention, what I claim as new is-' The flange andrack e, dependent from the bed-plate By, and the roller f, and the barg, in combination withthe brace h and shaft H of the wheel N,substantially as described.

ALEXANDRE GASTEL.
